- 論文の詳細を見る
Collimation effects on the coherent bremsstrahlung produced in a thin silicon crystal have been studied by using 1 BeV electrons whose angular divergence is suppressed by scrapers in synchrotron orbit. The energy spectra of the bremsstrahlung exhibited narrow spikes and large enhancement ratios. The full width at half-maximum of the enhanced spike of 15% has been obtained at the photon energy of 435 MeV. The observed spectra were fitted to the theoretical ones calculated by the least square method. The fit gives the effective collimation angle Θ_<eff> of 0.54 reduced angles. The continuous part was 1.85 times as large as the theoretical prediction. Considering that the mechanical collimation angle Θ_c is 0.32 reduced angles, Θ_<eff> is mainly ascribed to the calculated multiple scattering angle Θ_<ms> of 0.65 reduced angles as well as Θ_c.
